Martin Green, Bonhams’ whisky specialist in Edinburgh, said: “The Macallan 1926 60-year-old has been described as the Holy Grail of whisky.

“Its exceptional rarity and quality puts it in a league of its own, and the world’s most serious whisky collectors will wait patiently for many years for a bottle to come on to the market.

“It is a great honour to be offering this amazingly rare whisky at our Edinburgh sale.”

Another bottle of The Macallan Valerio Adami 1926 was sold at Bonhams Hong Kong in May for a world record-breaking price of £814,081, the most paid for a bottle of Scotch whisky at public auction.

At the same sale, Bonhams also sold a bottle of The Macallan Peter Blake 1926 60-year-old for £751,703.

A number of other important bottles are also being offered for sale at the Edinburgh auction next week.

They include three bottles of Black Bowmore 1964, estimated to fetch £42,000-£51,000; a Macallan 62-year-old from 1950, valued at up to £35,000; and a Dalmore 50-year-old from 1926, with an estimated hammer price of £20,000-£25,000.
